Introduction; Radeye B20/-Er Db-065 E - Thermo Scientific RadEye B20 Operating Instructions Manual

1. Introduction

The RadEye B20 and B20-ER are modern compact multi-
purpose contamination meters for alpha, beta, gamma and X-
ray radiation. By virtue of an optional gamma energy filter,
gamma dose rate measurements from 17 – 1300 keV can be
performed. For emergency response purposes alpha and beta
contamination can be discriminated using another optional
filter. In this context it is important to note, that users may
select "R/h" as a display unit, with the understanding that the
energy response characteristic is not altered by this selection.
Within the RadEye B20 the relation 1 R = 1 rem =10 mSv =
8.77 mGy/h is used.
The instrument incorporates a sensitive GM pancake tube
detector allowing the detection of low to medium radiation
levels.
The last 1600 mean and maximum values of the count rate or
dose rate are recorded internally and can be read out via serial
interface. Additionally the RadEye B20 logs the last 250
alarms, errors and changes of the configuration. All events can
be read out via serial interface.
